○○○ synchronous ⪢⪢
Because the moon's period of rotation is equal to its period of revolution, that is to say, because the moon takes the same amount of time to spin as it does to orbit the earth, we from the earth only ever see one face of the moon.

○○○ heliocentric ⪢⪢
In a heliocentric model the Sun, not the Earth, is in the center and all other objects including the Earth orbit the Sun. In this model the Earth is moving in two ways. It revolves arround the Sun and it also rotates on an axis. → spin
